Characteristics of heat-treated aluminum alloy introduced

Aluminum heat treatment Features: For high carbon steels, after quenching immediate access to a high hardness, and ductility of aluminum is very low, however, and otherwise, just after the aluminum alloy quenching, strength and hardness does not immediately rise. high, as the plastic did not decrease, but increased. but this alloy after quenching, place some time (such as 4-6 days and nights), strength and hardness will be significantly improved, and significantly reduced ductility alloy after quenching strength, hardness increased significantly with increasing phenomenon, known as aging over time. aging can occur at room temperature, called natural aging, can also occur within a certain temperature range above room temperature (such as 100 ~ 200 ℃), said artificial aging.
